iPad Which video apps that can search for a keyword in the transcript and play them automatically?

[Sodium Chloride]

I have about 50 video files with separate transcript (srt) files. These are video lectures that I downloaded from YouTube and elsewhere. Let’s say I want to play a video where the professor says the word “coefficient”. Is there any app that can search which file in which the professor says the word coefficient and play them right at the time when the professor says the word?

I don't think there is any app capable of doing that but you may be able to create a shortcut that can do it.
